How long owners hold.

The median Prop 13 base year for apartment parcels in 91321 Santa Clarita is 2004. A base year resets when a building sells, so an old one usually means the same owner or the same family has held it a long time.

84 parcels, 30%, still carry a base year of 1995 or earlier. The figure for all 255 ZIP codes here is 28%, so owners in 91321 Santa Clarita have held about as long as the average.

Long-held buildings often pay property tax on a value set decades ago. When they sell, the new owner is taxed on the price, which is part of why rents and expenses on these buildings need a close look before anyone sets a price.

How often buildings sell.

By last recorded transfer, 11 apartment parcels in 91321 Santa Clarita changed hands in 2022, 8 in 2023 and 18 in 2024.

That is 6.5% of the parcels here, against 7.3% across all 255 ZIP codes, so buildings here turned over at about the same rate as the average.

A building that sold twice in those years shows up once, in its later year, and a transfer is not always a sale at market. A move into a trust or between family members is recorded too.
